QID 354717: Amazon Linux Security Advisory for sudo : ALAS-2023-1682

In sudo before 1.9.12p2, the sudoedit (aka -e) feature mishandles extra arguments passed in the user-provided environment variables (sudo_editor, visual, and editor), allowing a local attacker to append arbitrary entries to the list of files to process.
This can lead to privilege escalation.
Affected versions are 1.8.0 through 1.9.12.p1.
The problem exists because a user-specified editor may contain a "--" argument that defeats a protection mechanism, e.g., an editor='vim -- /path/to/extra/file' value. (
